FIG. 1 is a view illustrating principle of a system for preventing disaster for a skyscraper according to one example embodiment of the present invention.

As shown in FIG. 1, since the skyscraper 100 has high height, it is swung the front and the rear or left and right in accordance with a wind 102, i.e. wind pressure. That is, displacement of the skyscraper 100 is changed. Here, the skyscraper 100 does not envisage a danger in case of low wind pressure, but it may envisage a danger in case that unexpected great wind pressure such as typhoon, etc. due to global warming occurs.

Accordingly, the system of preventing disaster of the present embodiment detects displacement (e.g. tilting angle) of the skyscraper 100, and compensates the displacement of the skyscraper 100 in case that the detected displacement is more than a reference value. For example, in case that the skyscraper 100 is slant in the right direction 104 by high wind pressure as shown in FIG. 1, the system of preventing disaster controls to shift the skyscraper 100 in the direction 106 opposed to the right direction 104 (swing direction). In one embodiment of the present embodiment, the system shifts the skyscraper 100 in the desired direction by pulling the skyscraper 100, i.e. applying tension in the gravity direction. As a result, the skyscraper 100 does not swing seriously (has small displacement change) though high wind pressure occurs, and so its safety may enhance and people therein may not envisage a danger. A process of compensating the displacement of the skyscraper 100 will be described in detail with reference to accompanying drawings.

Hereinafter, a process of detecting the displacement (tilting angle) performed before compensating the displacement of the skyscraper 100 will be described in detail.

FIG. 2 and FIG. 3 are views illustrating a process of detecting the displacement of a skyscraper according to one example embodiment of the present invention.

In a first method of detecting the displacement, the system of present embodiment detects the displacement of the skyscraper 100 using a GPS system as following.

In FIG. 2(A), GPS modules 200 for GPS communication are set to several places of the skyscraper 100. For example, the GPS modules 200 may be set to corners of the skyscraper 100 as shown in FIG. 2(B).

Each of the GPS modules 200 communicates with a GPS satellite (not shown), and detects its coordinates through the GPS satellite. Since the GPS modules 200 are set to several places of the skyscraper 100 as shown in FIG. 2(A) and FIG. 2(B), the GPS modules 200 forms one network. As a result, in case that present coordinates of the GPS modules 200 are detected, the system of the present embodiment may detect total location change of the skyscraper 100 through the detected present coordinates. In other words, the system may detect the displacement, i.e. tilting angle of the skyscraper 100 through the location change of the GPS modules 200.

Each of the GPS modules 200 transmits the detected present coordinates to a central management module as described below. The central management module detects the displacement of the skyscraper 100 through the transmitted coordinates.

However, it is difficult to use the method of detecting the displacement of the skyscraper 100 through the GPS communication if the GPS communication can't be performed or the GPS module 200 has low reception ratio.

Accordingly, the system of the present invention provides further a method of detecting the displacement of the skyscraper 100 using a laser as well as the GPS communication method.

Now referring to FIG. 2(A), specific space 202 is formed inside the skyscraper 100. Structure and disposition of the space 200 will be variously modified as long as a laser beam 302 is delivered to an upper part of the space 202 from a lower part of the space 202.

A laser module locates in the lower part of the space 202, and outputs the laser beam 302 to the upper part of the space 202 in the space 202. That is, the laser module outputs the laser beam 302 to the upper part in the space 202 as shown in FIG. 3. Since a laser sensing module 300 is set in the upper part of the space 202, e.g. end of the upper part, the system may detect the displacement of the skyscraper 100 through location of the laser beam 302 received to the laser sensing module 300. For instance, the laser beam 302 is incident to a center of the laser sensing module 300 as shown in FIG. 3(A) in case that the skyscraper 100 does not swing, but is incident to a point out of the center of the laser sensing module 300 as shown in FIG. 3(B) in case that the skyscraper 100 swings in accordance with the wind pressure. Hence, the system for preventing disaster may detect the displacement of the skyscraper through deviation of incident point.

In another embodiment of the present invention, the laser module may locate in the upper part of the space 202, and the laser sensing module 300 may locate in the lower part of the space 202. In other words, the location of the laser module and the laser sensing module 300, etc. may be variously modified as long as the system may detect the displacement of the skyscraper 100 using the laser beam 302.

FIG. 2 shows the space 202 formed to a top part from a ground. However, structure of the space 202 may be variously modified as long as the system may detect the displacement of the skyscraper 100 using the laser beam 302. For example, the space 202 is extended to the top part from a middle part of the skyscraper 100. It is desirable that the space 202 is formed to the top part from the ground in consideration of a process of establishing the skyscraper 100.

In brief, the system for preventing disaster of the present embodiment detects the displacement of the skyscraper 100 using the GPS communication method and the laser sensing method. Here, the system may use both of the GPS communication method and the laser sensing method, or use only one of the GPS communication method and the laser sensing method.

In another embodiment of the present invention, the system for preventing disaster sets three first communication devices in the skyscraper 100 and sets three second communication devices outside the skyscraper 100, and may detect displacement of the skyscraper 100 through triangulation. That is, various methods may be used as long as they detect the displacement of the skyscraper 100.

In case that the wind pressure affects to the skyscraper 100, the skyscraper 100 swings and deformation may occur to several parts of the skyscraper 100. Accordingly, the system of the present embodiment may use also a stress sensor for sensing the deformation (stress).

Particularly, stress sensors, e.g. optical fiber sensors (specially fiber brag grating sensor, in which gratings are included in one optical fiber, having high sensitivity without being interfered by electromagnetic) for sensing stress through wavelength change in accordance with outside condition may be set to the parts of the skyscraper 100. The stress sensors sense stresses of the skyscraper 100 in accordance with the wind pressure, and transmits the sensed result to the central management module. The central management module analyzes the transmitted result, thereby detecting total stress (deformation) of the skyscraper 100.

In one embodiment of the present invention, the system of the present invention synthesizes information concerning the stresses of the parts of the skyscraper 100, and may display the synthesized result with color. For example, a part of the skyscraper 100 to which much deformation occurs is displayed with red color, and a part of the skyscraper 100 to which deformation little occurs is displayed with blue color. As a result, a manager may catch easily state of the skyscraper 100.

As described above, the system of the present invention detects the displacement (tilting angle) and total stress of the skyscraper 100 through various methods. In one embodiment of the present invention, the system may display the detected displacement through 3D image so that the manager catch easily the detected displacement, and display the total stress of the skyscraper 100 with color in the 3D image.

FIG. 4 is a block diagram illustrating a system for preventing disaster according to one example embodiment of the present invention.

In FIG. 4, the system of the present embodiment is set to the skyscraper 100, and includes at least one GPS module 200, a laser sensing module 300, at least one fiber bragg grating sensor 400, a central management module 402 and a displacement compensating apparatus 404.

The GPS module 200 detects present coordinates by communicating with a GPS satellite, and transmits the detected result to the central management module 402 through wireless or wire communication.

The laser sensing module 300 senses a laser beam outputted from a laser module, and transmits the sensed result to the central management module 402 through wireless or wire communication.

The fiber bragg grating sensor 400 as the stress sensor (stress measuring module) senses stress of the skyscraper 100 through wavelength change of a light, and transmits the sensed result to the central management module 402 through an optical fiber, wireless communication or wire communication. Here, the fiber bragg grating sensors 400 sense stress using fiber grating (short-period fiber grating, long-period fiber grating, chirped fiber grating, etc.) and are usually set in concrete of the skyscraper 100. Number and disposition of the fiber bragg grating sensors 400 may be various modified in accordance with object of a manager.

The central management module 402 synthesizes the results (information) transmitted from the GPS module 200, the laser sensing module 300 and the fiber bragg grating sensor 400, detects present state of the skyscraper 100 on the basis of the synthesized results, and provides the state of the skyscraper 100 to the manager. It is desirable that the central management module 402 displays the state of the skyscraper 100 through the 3D image and shows the stress sensed by the fiber bragg grating sensor 400 with color. As a result, the manager may catch easily and quickly the state of the skyscraper 100, and may compensate the displacement of the skyscraper 100 or repair a part of the skyscraper 100 determined as danger due to serious stress.

For example, the central management module 402 controls the displacement compensating apparatus 404 in case that the displacement of the skyscraper 100 is more than a reference value, thereby pulling the skyscraper 100 in the gravity direction. Here, the control process may be manually performed by the manager, or may be automatically performed by the central management module 402 in consideration of characteristic of the system for preventing disaster.

In addition, the central management module 402 may locate in the skyscraper 100, or locate outside the skyscraper 100. It is desirable that the central management module 402 locates in the skyscraper 100 in view of management.

The displacement compensating apparatus 404 compensates the displacement of the skyscraper 100 in accordance with control of the central management module 402. For example, in case that the displacement (tilting angle) of the skyscraper 100 is more than the reference value (reference tilting angle) due to high wind pressure, the displacement compensating apparatus 404 pulls the skyscraper 100 in the gravity direction. Subsequently, in case that the displacement of the skyscraper is changed to a value less than the reference value according as the wind is weak, the displacement compensating apparatus 404 cancels the pulling force.

Hereinafter, detail structure and operation process of the displacement compensating apparatus 404 will be described in detail with reference to accompanying drawings.

FIG. 5 is a view illustrating schematically a displacement compensating apparatus according to one example embodiment of the present invention.

As shown in FIG. 5, the system of preventing disaster of the present embodiment pulls the skyscraper 100 in the gravity direction using the displacement compensating apparatus 404 in case that the displacement of the skyscraper 100 is more than the reference value.

In one embodiment of the present invention, the displacement compensating apparatus 404 includes anchor structures 500 a to 500 f. The system controls the anchor structures 500 a to 500 f so that some of the anchor structures 500 a to 500 f pull the skyscraper 100 in the gravity direction as shown in FIG. 5 when the system compensates the displacement. For example, in case that the skyscraper 100 is inclined in the right direction by the wind pressure, the system controls the anchor structures 500 a to 500 f so that only left anchor structures 500 a to 500 c of the anchor structures 500 a to 500 f pull the skyscraper 100 in the gravity direction.

On the other hand, since the skyscraper 100 has various structures, disposition and number, etc. of the anchor structures will be designed properly in accordance with structure of the skyscraper 100.

Hereinafter, the anchor structures 500 will be described in detail.

FIG. 6 and FIG. 7 are views illustrating an anchor structure and a hydraulic module according to one example embodiment of the present invention.

The anchor structure 500 has an upper part shown in FIG. 6(A) and a lower part shown in FIG. 6(B). Here, the upper part of the anchor structure 500 locates over the ground floor, and the lower part of the anchor structure 500 locates under the ground floor of the skyscraper 100.

Hereinafter, the upper part and the lower part of the anchor structure 500 will be described in detail.

An end part 600 of the upper part of the anchor structure 500, i.e. upper fixing section has a structure shown in FIG. 6, and may be set to “A” part (shown in FIG. 5) of the skyscraper 100. Shape and set method of the upper fixing section 600 may be variously modified as long as the anchor structure 500 is fixed to the skyscraper 100 through the upper fixing section 600 and anchor structure 500 can pull the skyscraper 100 in the gravity direction.

The upper fixing section 600 of the anchor structure 500 is connected to the lower part of the anchor structure 500 through an anchor cable 602. Here, the anchor cable 602 includes an anchor wire 610 for tension and a sheath pipe 612 for protecting the anchor wire 610 as shown in FIG. 6(B).

In FIG. 7, the anchor cable 602 extended under the ground floor of the skyscraper 100 is connected to a tension section 704.

The tension section 704 moves up or down in accordance with oil pressure under the condition that it is inserted into a hydraulic cylinder 700. That is, the tension section 704 functions a piston, and may be made up of for example a PC steel bar.

Hydraulic fluid 702 is included in the hydraulic cylinder 700, and the tension section 704 functioning as the piston goes up or down in accordance with movement of the hydraulic fluid 702.

A lower fixing section 706 is connected to a lower part of the hydraulic cylinder 700. Here, the lower fixing section 706 is inserted into a ground, and supports the anchor structure 500.

In other words, the anchor structure 500 includes the lower fixing section 706, the hydraulic cylinder 700, the tension section 704, the anchor cable 602 and the upper fixing section 600 disposed in sequence from the lower part. The anchor structure 500 is fixed to the skyscraper 100 through the lower fixing section 706 and the upper fixing section 600, and the tension section 704 changes to compensate the displacement of the skyscraper 100. Particularly, in case that the system of preventing disaster pulls the skyscraper 100 in the gravity direction to compensate the displacement of the skyscraper 100, it controls the anchor structure 500 so that the hydraulic fluid 702 in the hydraulic cylinder 700 flows down and so the tension section 704 moves in the gravity direction. As a result, the anchor wire 610 of the anchor cable 602 is pulled in the gravity direction, and thus the skyscraper 100 is pulled in the gravity direction.

Hereinafter, a method of providing the tension to the anchor structure 500 will be described in detail.

Now referring to FIG. 7, the hydraulic cylinder 700 is connected to the hydraulic controlling section 714, the hydraulic pump 712 and the hydraulic tank 710 through transport pipes.

The hydraulic tank 710 stores the hydraulic fluid 702.

The hydraulic pump 712 is connected to the hydraulic tank 710, and pumps the hydraulic fluid 702.

The hydraulic controlling section 714 adjusts the hydraulic fluid 702 pumped by the hydraulic pump 712, and then supplies the hydraulic fluid 702 to the hydraulic cylinder 700. Specially, the hydraulic controlling section 714 may be directly controlled by the central management module 402.

A gate valve 716 controls the hydraulic fluid 702 so that the hydraulic fluid 702 supplied from the hydraulic controlling section 712 flows in desired direction, and may be for example solenoid valve. Particularly, in case of moving the tension section 704 in the gravity direction, the gate valve 716 controls the hydraulic fluid 702 so that the hydraulic fluid 702 is supplied on the hydraulic cylinder 700 as shown in FIG. 7. Whereas, in case of moving the tension section 704 in the direction opposed to the gravity direction, the gate valve 716 controls the hydraulic fluid 702 so that the hydraulic fluid 702 is supplied below the hydraulic cylinder 700.

A drain valve 718 controls the hydraulic fluid 702 between the hydraulic tank 710 and the hydraulic cylinder 700. For example, since the tension section 704 moves in the gravity direction when the hydraulic fluid 702 is supplied on the hydraulic cylinder 700, the drain valve 718 controls the hydraulic fluid 702 so that the hydraulic fluid 702 existed below the hydraulic cylinder 700 flows to the hydraulic tank 710.

In brief, the system of preventing disaster of the present embodiment pulls the skyscraper 100 in the gravity direction by using the hydraulic system so as to compensate the displacement of the skyscraper 100, thereby keeping safely the skyscraper 100. Specially, in case that the system of preventing disaster determines to compensate the displacement of the skyscraper 100 through measurement of the tilting angle of the skyscraper 100, the system may control automatically the hydraulic system irrespective of the manager's command.

In above description, the system of preventing disaster uses the hydraulic method to compensate the displacement of the skyscraper 100. However, the system may use other compensating methods such as a method using an electric motor, etc.

FIG. 8 is a flow chart illustrating a method of compensating the displacement of a skyscraper according to one example embodiment of the present invention.

In FIG. 8, the central management module 402 collects the information transmitted from the GPS module 200, the laser sensing module 300 and a stress measuring module (the fiber bragg grating sensor) 400, and measures displacement of the skyscraper 100, e.g. a tilting angle in accordance with a wind pressure through the collected information in step of S800.

In step of S802, the central management module 402 detects whether or not the measured tilting angle is more than a reference angle.

In case that the measured tilting angle is smaller than the reference angle, the step S800 is again performed. That is, since the skyscraper 100 does not envisage a danger by wind, the central management module 402 monitors continuously the wind pressure without compensating the displacement of the skyscraper 100.

In case that the measured tilting angle is more than the reference angle, the central management module 402 detects displacement (tilting angle), direction and stress, etc. of the skyscraper 100 through analysis of the collected information to compensate the displacement of the skyscraper 100 in step of S804.

In step of S806, the central management module 402 selects some of the anchor structures 500 to which tension is to be applied in accordance with the detected result.

In step of S808, the selected anchor structures pull the skyscraper 100 in the gravity direction in accordance with control of the central management module 402, thereby compensating the displacement of the skyscraper 100. Here, the tension may be varied in accordance with the wind pressure. In addition, tensions of the anchor structures may be the same or differ.

In step of S810, the central management module 402 measures the displacement of the skyscraper 100, e.g. tilting angle through information collected from the GPS module 200, the laser sensing module 300 and the stress measuring module 400, and detects whether or not the measured tilting angle is smaller than the reference angle.

In case that the measured tilting angle is more than the reference angle, the step S808 is continuously performed because the wind affects to the skyscraper 100.

In case that the measured tilting angle is smaller than the reference angle, the anchor structures related to the tension are returned to initial condition in step of S812. That is, the anchor structures for pulling the skyscraper 100 in the gravity direction cancel the tension.
